i trying work endless adapter , followed example
http://droidista.blogspot.com/2011/04/using-cwacs-endlessadapter-with-custom.html
and
i have tried code
public class mainactivity extends activity { static int list_size; private int mlastoffset = 0; static final int batch_size = 10; private rotateanimation rotate = null; arraylist<string> templist = new arraylist<string>(); string[] product = new string[]{"p1" , "p2" , "p3" , "p4" , "p5" ,"p6" , "p7" , "p8" , "p9" , "p10" , "p11" ,"p12" , "p13" , "p14" , "p15" , "p16" , "p17" ,"p18" , "p19" , "p20" , "p21" , "p22" , "p23" ,"p24" , "p1" , "p2" , "p3" , "p4" , "p5" ,"p6" , "p7" , "p8" , "p9" , "p10" , "p11" ,"p12" , "p13" , "p14" , "p15" , "p16" , "p17" ,"p18" , "p19" , "p20" , "p21" , "p22" , "p23" ,"p24" , "val1" , "val2" , "val3" , "val4" , "val5" ,"val6" , "val7" , "val8" , "val9" , "val10" , "val11" ,"val12" , "val13" , "val14" , "val15" , "val16" , "val17" ,"val18" , "val19" , "val20" , "val21" , "val22" , "val23" ,"val24" , "val1" , "val2" , "val3" , "val4" , "val5" ,"val6" , "val7" , "val8" , "val9" , "val10" , "val11" ,"val12" , "val13" , "val14" , "val15" , "val16" , "val17" ,"val18" , "val19" , "val20" , "val21" , "val22" , "val23" ,"val24"}; string[] shop_items = new string[]{"val1" , "val2" , "val3" , "val4" , "val5" ,"val6" , "val7" , "val8" , "val9" , "val10" , "val11" ,"val12" , "val13" , "val14" , "val15" , "val16" , "val17" ,"val18" , "val19" , "val20" , "val21" , "val22" , "val23" ,"val24" , "val1" , "val2" , "val3" , "val4" , "val5" ,"val6" , "val7" , "val8" , "val9" , "val10" , "val11" ,"val12" , "val13" , "val14" , "val15" , "val16" , "val17" ,"val18" , "val19" , "val20" , "val21" , "val22" , "val23" ,"val24" , "p1" , "p2" , "p3" , "p4" , "p5" ,"p6" , "p7" , "p8" , "p9" , "p10" , "p11" ,"p12" , "p13" , "p14" , "p15" , "p16" , "p17" ,"p18" , "p19" , "p20" , "p21" , "p22" , "p23" ,"p24" , "p1" , "p2" , "p3" , "p4" , "p5" ,"p6" , "p7" , "p8" , "p9" , "p10" , "p11" ,"p12" , "p13" , "p14" , "p15" , "p16" , "p17" ,"p18" , "p19" , "p20" , "p21" , "p22" , "p23" ,"p24"}; arraylist<string> prodcutlist1 = new arraylist<string>(); arraylist<string> vallist1 = new arraylist<string>(); listview simplelist ; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); simplelist = (listview)findviewbyid(r.id.listview1); init(); //displaylist(); (int i=0; i<product.length; i++){ vallist1.add(product[i]); } } private void init() { list_size = shop_items.length; (int i=0; i<=batch_size; i++){ prodcutlist1.add(shop_items[i]); // vallist1.add(product[i]); } setlastoffset(batch_size); displaylist(prodcutlist1); } private void setlastoffset(int i) { mlastoffset = i; } private int getlastoffset(){ return mlastoffset; } private void displaylist(arraylist<string> prodcutlist1) { simplelist.setadapter(new demoadapter()); } private class customarrayadapter extends arrayadapter<string>{ public customarrayadapter(context context, int resource, int textviewresourceid, list<string> objects) { super(context, resource, textviewresourceid, objects); } @override public view getview(int position, view convertview, viewgroup parent) { viewholder holder; if(convertview==null){ layoutinflater inflater = (layoutinflater) mainactivity.this.getsystemservice(context.layout_inflater_service); convertview = inflater.inflate(r.layout.set_aside_items, null); holder = new viewholder(); holder.word = (textview)convertview.findviewbyid(r.id.producttitle); holder.world = (textview)convertview.findviewbyid(r.id.price); convertview.settag(holder); } else{ holder=(viewholder)convertview.gettag(); } holder.word.settext(string.valueof(position+1) + ".
